I have owned an Eastman Concert (EUC) for about a year now, and I am very happy with it. All solid wood, excellent construction, classic mahogany tone. These are styled very similarly to vintage Martins, and deliver a very comparable tone. I think the Eastmans are one of the great bargains in the uke world right now, but they don't seem to have caught on. Part of that is limited product line (they are only making mahogany ukes), but I think the biggest issue is not many dealers are carrying them, so not many people have tried them.
